UNITED STATES JOHN WASHCO, OF WILKES-BARBIE, PENNSYLVANIA.

SHOEMAKERS' TOOL.

Application filed October 13, 1924. Serial No. 743,377.

To all whom it may concern:

Be it known that I, JOHN Wnsrroo, a citizen of the United States ofAmerica, and resident of l/Vilkes-Barre, in the county of Luzerne andState of Pennsylvania, have invented certain new and useful Improvementsin Shoemakers Tools, of which the following is a specification.

This invention relates to shoemakers tools, and has for an object theprovision of novel means for cutting grooves or seats in the outersurfaces of soles of shoes to receive fastenings, such as stitching orthe heads of nails, by which the sole of the shoe is secured in place.

It is an object of this invention to provide a tool, the cutting bladeof which will be guided to travel parallel with or concentric to theedge of the sole and operative to produce an incision or out which isdiagonal to the edge of the sole.

It is the purpose of this inventor to pro duce a knife or blade whichwill produce an undercut in the sole in order that the leather may beturned up and back to produce a channel in which the sole fastenings,whether stitching, nails or pegs, may be imbedded and concealed when theleather which has been displaced to form the channel is replaced andsecured by appropriate,

adhesive.

It is a further object of this invention to produce a cutter of thecharacter indicated having a blade with a cutting edge in such relationto a guide as to insure proper undercutting when the slit is being made.

It is a still further object of this invention to produce a blade whichis removably secured to the body of the cutter in order that the saidblade may be removed for the purpose of sharpening it, or to renewblades that have become impaired or worn. It is a still further objectof this invention to associate with the cutter of the characterindicated a leather engaging device which may be used as a screw driveror for displacing the leather after the sole has been out.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this application wherein likecharacters denote corresponding parts in the several views, and inwhichi Figure 1 illustrates a view in elevation of a cutting toolembodying the invention;

Figure 2 illustrates an end view thereof; Figure 3 illustrates aperspective view of the blade or knife; and

Figures 4 and 5' are perspective views illustrating the application ofthe invention during the cutting and leather manipulating processes.

In these drawings, 10 denotes a head having a shank 11, which may besecured in any suitable handle such as 12. The shank and. the handle aredetails of construction which may be changed to suit particularrequirements, and need not be described more fully. The head 1.0 has aflat curved extension 13, the end 1 1 of which constitutes a guide whichis intended to engage the edge of the sole of a shoe when the cutter isbeing used. The extension 13 has a recess or notch 15 formed in its edgewhich produces a clearance for the blade or knife 16. The blade or knifehas a shankor plate 17 integral with it that is secured to the extension13 by fastenings 18, such as screws or the like, so that by theremovalof the screws, the blade may be removed for the purpose asstated.

It will be seen from an inspection of the drawing that the blade properextends diagonally with relation to the plate or shank 17 and withrelation to the surface of the guide 14:. This relation of parts permitsthe guide to engage and ride along the edge of the sole of the shoewhile the knife or blade is extending downwardly and inwardly withrelation to the said edge. The result ofthe operation of the device whenworking on soles of shoes is that the knife will extend inwardly anddownwardly to produce an undercut in the sole of the shoe in order thatthe leather may be displaced by forcing it upwardly and inwardly to forma channel 19, in which stitching or nails will be imbedded. Thereafterthe displaced leather will be returned to its normal position to coverthe stitching and to conceal the fastenings.

The head has an integral extension 20 which may be used as a screwdriver, or it maybe inserted in the cut produced by the knife todisplace the material when the channel is being formed.

The head of the tool and the integral parts thereof may be formed byordinary stamping processes, and therefore, the device can bemanufactured expeditiously and at cornparatively small cost.

I claim: c 1. In a sole cutting tool, a head having a flat extensionWhose end constitutes a guide,v

the said extension having its edge recessed to form a seat, a platesecured to the head and extending to the recess, a blade integral withthe plate extending diagonally with respect to the said plate throughthe seat of the extension, and means lor securing the plate to the head;

2, In a sole cutting tool, a plate-like head having a flat plate-likelateral extension with a recess in its edge, the said extension beyondthe recess constituting a guide, a plate lying against the head andsecured thereto,

a blade integral with the plate and extending diagonally with respect tothe plate, the

said blade projecting through the recess of the guide and terminatingbeyond the side surface of the gulde, and means for securing the plateto the head.

JOHN Was'nco.
